Bullet Proof Diesel Square EGR Cooler NT-EGRC-1 for 6.0L Powerstroke

Stop the cycle of failed factory EGR coolers on your 6.0L Powerstroke. The Bullet Proof Diesel NT-EGRC-1 square-style cooler is a proven, upgraded replacement that addresses the well-known weaknesses of the OEM unit—cracking, leaks, coolant loss, and the risk of hydrolock.

This cooler uses stronger stainless steel tubing and fully TIG-welded construction for greater resistance to heat stress and fatigue. It is a direct-fit replacement that works with your factory EGR system, requires no tuning or modifications, and will not trigger check-engine lights. It remains emissions-compliant (CARB D-730) and is legal for use in all 50 states.

Key Features

• Stainless steel tubing built for durability and heat resistance
• All joints and seams TIG welded
• Direct-fit replacement with consistent quality control
• Compatible with stock ECM, chips, and tuners
• Lifetime parts-only warranty
• Helps prevent major engine damage from a failed OEM cooler

Fitment Fits 6.0L Ford Powerstroke engines built on or after 9/22/03 (square-style cooler). Compatible with:

• F-Series: 2004.25–2007
• E-Series: 2004.25–2010
• Excursion: 2004.25–2005

Replaces OEM part numbers including 4C3Z-9P456-AC, 4C3Z9P456AA, 4C3Z9P456AH, 4C3Z9P456AF, 4C3Z9P456AJ, 1845145C96, 1845145C97, 1845145C99, and similar.

Important Notes Gaskets are not included and must be purchased separately. It is strongly recommended to replace the engine oil cooler at the same time, as restricted coolant flow from a failing oil cooler is a common cause of EGR cooler failure.

This upgrade has been trusted by thousands of 6.0L owners since 2008 as a long-term solution instead of repeated OEM replacements.
